Cool chart. Any chance of getting the popular oil stones and Arkansas stones added to the list and a spreadsheet or pdf download?

May want to attach it to the forum so its hosted here and not some place where it can disappear. Every forum that was using it was just pointing to it so when it went away it went away from everywhere.

From research done on another thread I can confirm the following from Boride Abrasives regarding the stock EP stones;

"Yes, Boride’s stones conform to the FEPA-F standard.

Average Particle Size
1000 Grit – 5 microns
1200 Grit – 3 microns

Please let me know if you need additional information and I will be happy to help"

I'm happy to forward the email to whoever if that would be helpful

Thanks

I'm not sure I'm reading & interpolating this chart correctly, perhaps someone with more experience can help. Does this chart identify the Shapton 1000 grit/micron between an interpolated 700-800 Chosera stone? Is the Shapton 4000 grit/micron just slightly less than a Chosera 3000 stone and the 6000 Shapton slightly less than the 5000 Chosera?

You got it! I personally take this chart as an approximation for most values, not a thoroughly scientifically researched, totally objective reference. It provides a good basis for comparison, though, between some popular stone lines.
